I drove by today, the rest stop is closed due to roadwork.
In the Fastned app it's correctly shown all out of service, but on IchTankeStrom one charger is stuck in available status.
The rest stop must be closed since 2025-07-10 because there are no sessions since that day on IchTankeStrom and it's been shown occupied 24/7 in other roaming apps.
Given charger 3/4 went out of service prior to the road closure, there was probably some sort of defect. We'll need to wait for the re-opening to see whether they already fixed it or not.
